METHOD FOR PERFORMING MU-MIMO BEAMFORMING TRAINING IN WIRELESS LAN SYSTEM, AND METHOD AND DEVICE FOR SUPPORTING MU-MIMO BEAMFORMING TRAINING

摘要

The present invention relates to a method for performing MU-MIMO beamforming training, the method comprising: receiving a MIMO beamforming setup frame including identification information of a station participating in MU-MIMO beamforming training, in an MU-MIMO beamforming setup subphase; receiving a BRP frame in an MU-MIMO beamforming training subphase; and performing MU-MIMO beamforming training using the BRP frame, if the identification information of the station included in the MIMO beamforming setup frame responds to the STA and a TA field and an RA field of the BRP frame are the same as a MAC address of an initiator that has transmitted the MIMO beamforming setup frame.
